"Pitcher Bob Hall, one of seven players turned over to the Brewers by the Braves last week, will not remain with the club, [Manager Charlie] Grimm revealed. Hall started the season with Milwaukee in 1951 but lasted only a month. He then joined Seattle, Highly temperamental, Hall is not the Grimm type of ballplayer, and the Brewer manager advised against rejoining the club. He will be sold or traded."

“Bob Hall, the 29-year-old righthand pitcher sold back by
the Bucs to Seattle of the Pacific Coast League on May 14, has been ordered
returned to the Bucs by Ford Frick, baseball commissioner.”

“Purchase of the pitcher by Seattle has been canceled by the
commissioner who, in a telegram to Branch Rickey of the Pirates, said the Bucs
had received a price in excess of that permitted by league rules.”

Oops. So Hall stayed with the Pirates for the whole season, posting a 3-12 mark and a 5.39 ERA. Thank you Mr. Frick.

“Bob Hall, righthanded pitcher who was sent to Hollywood of
the Pacific Coast League on a look-see basis, and who was returned to the
Pirates a few days ago, was sold to Seattle of the PCL last night,”

Hall would finish in Portland and San Diego in the next two years, but those transactions haven't been found...yet!
